About the Y65 Code Range
These events occur during surgery or other medical care, such as transfusing mismatched blood or using the wrong fluid in an infusion.
Within Y65, subdivisions distinguish mismatched blood (Y65.0), wrong infusion fluid (Y65.1), and failed stitches or surgical ties (Y65.2). They also identify a misplaced breathing tube during anesthesia (Y65.3) and failure to insert or remove another tube or instrument (Y65.4).
The wrong-procedure branch (Y65.5) separates a wrong procedure on the correct patient (Y65.51) from a procedure on a patient not scheduled for surgery (Y65.52). It also identifies the correct procedure on the wrong side or body part (Y65.53). Other specified misadventures have Y65.8.
